As outside groups dump money into western New York largely to attack him, third-party candidate Jack Davis has loaned his campaign an additional $500,000, according to campaign records filed this week with the Federal Election Commission.

Davis has promised to spend $3 million in his quest to win the May 24 special election without any party backing. He qualified for the ballot by collecting signatures and will appear on the “Tea Party” line.

The new loans, $300,000 on Thursday and $200,000 on Monday, bring Davis’ total personal investment so far to $2.1 million.

Republican nominee and former business owner Jane Corwin had loaned her campaign $1 million through the end of March. Her updated pre-special-election filing, which may include further loans, is due this Thursday.

News of Davis’ new investment came the same day that outside conservative group American Crossroads reserved $650,000 in television advertising time in the 26th district, which includes the Buffalo and Rochester media markets.

Less than five hours after the Crossroads buy became public, a Democratic consultant confirmed that the Democratic Congressional Campaign Committee plans to spend $250,000 on the race.

Updated filings with the FEC show that Members of Congress and their friends are also starting to contribute to the campaigns.

On Thursday, Corwin received $5,000 from Rep. Kevin McCarthy’s (R-Calif.) political action committee, $2,000 from former Rep. Tom Reynolds’ (R-N.Y.) PAC and another $2,000 from former Reynolds aide Sally Vastola.

Democratic nominee Kathy Hochul received three $1,000 donations from Saturday to Monday from Reps. Paul Tonko (D-N.Y.), Allyson Schwartz (D-Penn.) and Louise Slaughter (D-N.Y.).

Davis is not seeking outside donations.
